1. What is the Irradiation Change Formula?

The Irradiation Change formula calculates the change in radiant flux (power) received by a surface per unit area based on resistance changes in a photoresistive transducer and its sensitivity to light intensity variations.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \Delta H \) — Irradiation Change (W/m²)
• \( \Delta R \) — Resistance Change (Ohm)
• \( \Delta S \) — Photoresistive Transducer Sensitivity

Explanation: The formula calculates irradiation change by dividing the resistance change by the sensitivity of the photoresistive transducer.

3. Importance of Irradiation Change Calculation

Details: Accurate irradiation change calculation is crucial for light sensing applications, optical measurements, and systems that require precise monitoring of light intensity variations.

4. Using the Calculator

Tips: Enter resistance change in Ohms and photoresistive transducer sensitivity. Both values must be positive numbers greater than zero.
